People, The Sun Java plugin which comes with JRE 6 does not work correctly in Firefox on several F7 machines I have here. It shows only a blank space at the place where an applet should be in web pages. No errors, no messages, but no applets :) There are a few F7 machines, however, where the plugin works fine, but I can't detect any difference between them and those where the plugin does not work. The plugin from JRE 5 works fine on all machines. Why is that? How can I make the plugin from JRE 6 to run consistently in Firefox on F7? Thanks, Marcelo
